DENTIFRICE COMPOSITION

摘要

A dentifrice composition which comprises (A) heavy calcium carbonate having a mean particle diameter of 5 to 15µm, (B) water-insoluble inorganic granules having a collapse strength of 10 to 200g/granule, a mean particle diameter of 50 to 150µm, and a difference of 100µm or below between 90% particle diameter and mean particle diameter, and (C) a water-soluble polymeric material comprising at least one member selected from Group (a) and at least one member selected from Group (b) at a (b)/(a) mass ratio of 0.25 to 3, Group (a): sodium alginate, sodium carboxymethylcellulose, methylcellulose, hydroxyethylcellulose, Xanthomonas campestris, ?-carrageenan, and straight-chain sodium polyacrylate, and Group (b): gellan gum, agar, ?-carrageenan, ?-carrageenan, gelatin, pectin, and crosslinked sodium polyacrylate, and which has a total content of (a) and (b) of 0.5 to 1.5% by mass based on the whole of the composition.
